Pitch Perfect's Rebel Wilson Dines with a Mystery Man

The Pitch Perfect star dined with a male companion Tuesday night at Basix Cafe in West Hollywood. The Aussie actress, clad in a leather jacket and with her hair in a ponytail, savored fries and a soda while inside the dimly lit eatery.

"She seemed totally laid-back and comfortable with her dinner guest," an onlooker, who describes the meal as "peaceful," tells PEOPLE. "They were involved in a long conversation and seemed close." – Dahvi Shira
